Satellite (GPS) compass - receiver or multi-receiver, which provides information about the course of the ship and other data. Electronic data can be displayed on the autopilot and the various remote displays. Satellite Compass uses signals from two or three GPS antennas. It is important that the antenna be definitely arranged and placed on a rigid platform, as analyzed the differences between the received signals to determine the exchange rate, and other parameters.

The latest generation of GPS-compass provides multiple programmable outputs and information about the course, the ship's position, as well as the vertical rolling. It can be installed on small vessels instead of gyro.

Installation Requirements :

When installing the satellite compass is necessary to take the 4 requirements :

Operation of the system based on GPS, it requires a clear sky visibility. When satellites are masked by deck superstructures, system performance may be impaired.

Make sure that the satellite compass is situated away from any other transmitting antennas on the vessel. The manufacturer specifies the characteristics of the device, which limits the distance allowed.

Position of satellite compass on board must be accurately known, especially on larger vessels. This information is important for systems programming, such as UAIS.

The platform on which the satellite compass, must be rigid and stable.

FURUNO SC-110

Description :

ACCURACY - 0.3 degrees !!!

The new processor device, provides the high level of accuracy and more perfect utilization properties.

Use of the 2-axial antenna, 3-axial high-speed gyroscope and accelerometers, allow to shorthand these, and advanced digital technologies of processing of a signal used in Furuno SC-30 with a high speed allow to calculate the data on a course based on indications of sensors with an extreme accuracy.

In standard complete use NMEA-2000 it is more easy for the installation, also optional can be connect interface unit IF-NMEASC for the convert to NMEA 0183, AD-10 contact group.

Four operating modes of the display: Compass, Control of the vessel, Navigation data, vessel Course .

Speed of tracking of change of course 25 deg/sec .

Can perform functions of the GPS navigator of 12 discrete channels .

Lack of mechanical parts, such as cardano suspension, saves from need of maintenance of a compass .

Typical approve on course trnslator according IMO MSC.116(73) .

The SC-50 model is the modern satellite compass developed based on original technology of the FURUNO "GPS kinematic" company. The compass is established on vessels of any types, and also on any other water or overland vehicles .

SC-50 consists of the antenna unit, display and the processor. The three-axis antenna system includes three antennas/receiver and can be delivered in the low-profile blister or as the antenna of open type. Such device of the antenna allows to reduce influence of rolling of the vessel .

JRC JLR-21/31

21 31

Description :

The JLR-31/JLR-21 supports Speed Over Ground (SOG) and Course Over Ground (COG). The position, SOG and COG are updated every 200 milliseconds (which is 5 times faster than previous model JLR-30/JLR-20), delivering high accuracy.

Traditionally, the means used to measure the heading of a ship has been a mechanical gyrocompass and/or a traditional magnetic compass. With the adoption of the new installation requirements in SOLAS-V, all passenger ships and all ships from 300 to 500 GT travelling international routes can now install a new technology directional sensor, the Transmitting Heading Device (THD).

JRC's new JLR-31/JLR-21, IMO type-approved as both Transmitting Heading Device (THD) and as Satellite Navigator (GPS), suits for the vessels as SOLAS-V required primary heading sensor or primary GPS.

Standard complete set :

Antenna unit for JLR-21 (diameter 691 mm) NNN-20 1 set .

Antenna unit for JLR-31 (diameter 1152 mm) NNN-30 1 set .
